Features | Hollow Rotary Actuators DGII Series

Features of Actuator Section

Take the AZ Series as an example, and show the features of the DGII Series.

Direct Load Fastening is Possible

Loads with large inertia such as tables and arms can be installed directly on the output table, eliminating the need for connecting parts (collars), reducing design and assembly effort and parts costs.

DG2 Series direct mounting

Large-Diameter Hollow Output Table

Hollow holes can be used for wiring cables and for air and liquid piping.

Diameter of Hollow Section
Example: DG200R
Applications
Filling Equipment With Piped-In Liquid

High Strength

Can Drive Heavy and Large Loads

Maximum permissible axial load is 4000 N. Maximum permissible moment is 100 N·m. It can drive even a load with a large mass or inertia.

Example Operation

Small Surface Runout

Loads can be placed away from the center of the output table.

Relationship between Load Moment and Displacement
Displacement at a Distance of L = 200 mm from the Center of the Table

High Positioning Accuracy

Motor Vertical Mounting Motor Horizontal Mounting
Backlash Non-backlash 6 arcmin (0.1°)
Repetitive Positioning Accuracy ±15 arcsec (±0.004°) ±30 arcsec (±0.008°)

Integrated Structure to Reduce Equipment Setup Time

Reduce the Time Required for "Design," "Assembly," and "Adjustment"

Equipment tables and arms can be installed directly on the output table.

Simplified Design

Advantages of Motor Horizontal Mounting

  • Machining of motor clearance hole is not necessary, thereby simplifying the installation plate.
  • Cables, pipes, etc. can be routed between the legs under the table.
Advantages of Motor Horizontal Mounting

Selectable Mounting Direction

The DGII Series can be installed horizontally, as well as on ceilings and walls, giving more options for equipment design.

Advantages of Equipping With αSTEP AZ Series

Battery-Free Absolute Encoder Equipped

It is equipped with a small battery-free mechanical absolute encoder (ABZO sensor). This can help improve productivity and reduce costs.

ABZO sensor
  • Mechanical-Type Sensor
    Retains positioning information even when power is not supplied
  • Multi-Rotation Absolute Encoder
    Absolute position detection is possible with ±900 (1,800) revolutions of the motor shaft from the home position

No External Sensors Required

As it is an absolute system, home sensors or limit sensors are not required.

Advantages

  • Improved High-Speed Return-to-Home + Return-to-Home Accuracy
  • Reduced Cost
  • Simple Wiring
  • Not Affected by External Sensor Malfunction

Battery-Free

Mechanical sensors do not require batteries.
Positioning information is managed mechanically by the ABZO Sensor.

Advantages

  • No need to replace batteries
  • Unlimited Driver Installation Possibilities
  • Safe for Overseas Shipping

Simplifying the Main Program via Sequence Function

The AZ Series come equipped with a wide variety of sequence functions such as timer settings for linked operation and during operations, conditional branching, and loop operation. (excluding some models)
It can be set up using the support software MEXE02, which simplifies the sequence program of the host system.

  • Positioning Operation Data Setting Value (max. 256)
  • General-Purpose I/O Signal Counts (Input 10, Output 6)
  • Communication I/O Signal Counts (Input 16, Output 16)

Convenient Operation and Setting

The AZ Series features allow you to drive:

Reduce Takt Time With Shortcut Operations

Move the shortest distance toward the set target position.

Reduce takt time with shortcut operations

Example)
Moving from the 0˚ position to 270˚, the shortest counterclockwise rotation direction is automatically selected and driven.

Set No-Entrance Area

Ensure equipment is not damaged by collisions with obstacles and work area is maintained.

Easy to Control by Setting the No-Entrance Area

Infinite Multi-Rotation is Possible

Equipped with a wrap function that can automatically reset the current position to "0°." Infinite multi-rotation operation is possible.

Reduces Equipment Setup Time

The parameters required to operate the hollow rotary actuator are set at the time of shipment. Contributes to reduced equipment setup time.

[Example of parameters set at the time of shipment]

  • Home position
  • Resolution (0.01°/step)
  • Setting the rotation direction of the output table
  • Wrap function setting (±180°)
  • *Each initial value can be changed.
Reduces Equipment Startup Time

Applications and Usage Examples

Applications Dealing With Load Moments

Applications Dealing With Load Moments

Low Speed and Low Vibration Applications

The microstep drive system and smooth drive function allow for low vibration rotary operation, even at low speeds.

Example) Liquid dispensing equipment

Even at low speed, stable and even dispensing is possible.

For High Precision Positioning Applications

It does not cause the phenomenon called "hunting," in which the shaft moves minutely when stopping. This is ideal for applications where vibration when stopping is a problem.

Example) Image inspection equipment

Accurate images can be captured because there is no hunting.

Applications With Varying Load Inertia

Since gain adjustment is not required, even for equipment with load fluctuations, can operate as set without the need for tuning.

Example) Disk manufacturing equipment

No tuning is required even if the number of discs to be transported changes.
